Two main instruments were used: a creative writing pre-test, and a creative writing post-test with a scoring rubric. Quantitative data analyses were conducted. T-test was used to compare the mean scores of the control group and the experimental one in the pre-post applications. Results showed that the experimental group pupils have developed their skills in memoir writing (eleven skills were developed while one skill is not). It was concluded that the "WebQuest" model was effective in fostering the memoir writing skills of the participants.
